[07:19] Quantum crashing. It's both crashed and not crashed at the same time.

[16:46] and atm it seems easiest to use different providers which is kind of a pita [16:50] i have PI space but no AS yet so no BGP for me yet [16:59] just a /24? [17:03] yes and a v6 /48 [17:07] oh yip [17:14] so.. I managed to get openvpn to provide ipv6 connectivity via a v4 tunnel [17:14] nice [17:14] now I am having issues getting Router Advertisements to work on a Linux box to provide addressing to LAN hosts [17:15] using radvd? [17:15] static IPv6 addressing works for hosts behind the tunnel too so thats cool [17:15] acf_: I guess thats what I was looking for, wasn't sure what it was called [17:15] this is my config: http://paste.unixcube.org/k/96bcb8 [17:15] /etc/radvd.conf [17:16] thanks [17:19] mnathani_: I'm guessing your client boxen are still mtu 1500.. [17:19] are you having any trouble accessing Google services? [17:19] you should definitely clamp [17:20] not really using this setup for any real users [17:20] mainly testing vms and cisco devices [17:21] I really should document the v6 over a v4 tunnel [17:22] can radvd provide ipv6 default gateway [17:23] yes [17:23] that configuration does ^ [17:27] you are right. It was a dns / ipv4 issue [17:29] I think radvd can do IPv6 DNS [17:30] 1452 is the highest packet size I can ping google with [17:52] is it necessary to set the mtu on each host, or only the host terminating the vpn? [18:44] mnathani_: if path mtu discovery works, just on your VPN endpoint interfaces [18:44] but Google doesn't appear to handle PMTUD correctly, at least for IPv6 [18:45] so you'd need to set the MTU on all of the hosts [18:45] in some tests I got upto 1402 [18:45] other tests 1452 [18:46] probably safe to set mtu to something like 1410 [18:46] yea [18:46] I use 1400 on mine, just to play it safe [18:46] does that set ipv4 and ipv6 at the same time? [18:46] or can you set them independently? [18:47] on Linux, that's the interface MTU [18:47] for all protocols [18:47] I remember setting the MTU on Windows, and I think you might be able to do it per protocol [18:47] I guess I could try and set separate interface for v4 and v6 [18:47] s/set/use [18:47] I guess I could try and use separate interface for v4 and v6 [18:53] (In theory, 1280 is the "safest bet" for ipv6 mtu, it's the minimum) [19:05] does mtu have an impact on maximum speed attainable on say a speed test? [19:11] Yes insomuch as it requires a higher packet rate to achieve the same bandwidth. [19:13] *** mnathani_ has quit IRC () [19:40] *** mnathani_ has joined #arpnetworks [19:41] brycec: gotcha [19:42] It's not likely to have any /real/ impact on your speed though. [19:42] it might for bittorrent [19:42] but not for normal traffic [19:42] well not much [19:43] And not on <100mbps pipes [19:43] well ipv6 does increase overhead [19:43] But if you're trying to sustain 1gbps for instance, then you start to care about your PPS a lot more. [19:43] 40 bytes for ip header, 20 bytes for tcp/ip, 12 bytes with tcp options [19:43] so that's 72 bytes.. [19:45] oh right [19:45] i would say not really depending on your system [19:45] coalescing mostly fixes it.

[20:31] we're live on the SSD now [20:31] gcc used to compile itself with itself after compiling itself with the system compiler [20:31] yeah, I think it did that [20:32] i haven't compiled it in years [20:32] now I'm building ffmpeg, and I can't figure out what needs it. [20:32] I should just uninstall it and see if anything complains. :) [20:32] i tried using gentoo years back [20:32] gnome took hours to buiild [20:33] "gentoo - for those times when your life isn't slow enough..." [20:33] it seemed like a good idea at the time [20:33] there was a lightning talk at SCaLE about picking a linux distro [20:33] it was pretty awesome [20:33] i am finding arch ok [20:35] yeah - the talks aren't archived online yet [20:35] I'm building packages at 730/hour :) [22:42] anyone pay for dropbox storage?
